Document Summary

Final: functions function declaration (or forward declaration) example: double max(double a, double b); Inputs (double a, double b) = parameters or arguments calling the function: max(3, c); double max(double a, double b) = function signature/prototype function definition: black box functionsignature { function body. View inputs and outputs, not internal workings.

A function definition can be provided in another file without being. #included: but must #include declarations (. h files) . h files = header files = contain declarations by convention. cpp files = cpp/source files = contain definitions by convention. One . cpp file must have one main function (usually main. cpp) . h files more readable than . cpp because declarations more concise than definitions scope.
